摘要
渭河作为陕西境内的主要河流,长期以来污染严重,宝鸡位于渭河陕西段上游,研究该段的水质及城市污水处理对水质的影响具有重要意义.采用一维多点稀释自净模型,以现有多年的水文及水质资料,预测了在各种保证率下修建城市污水厂对渭河水质改善程度.在分析渭河宝鸡市区段水污染状况的基础上,比较了宝鸡市建与不建污水厂对该段水质状况的影响.结合宝鸡市污水处理工程规划和生态城市建设规划,分析2020年宝鸡市污水处理工程全部建成后渭河宝鸡段水环境变化,认为宝鸡市污水处理工程建设对实现宝鸡市生态园林城市建设具有重要意义.
As the main river running across Shaanxi Province, the Weihe River has been polluted seriously. Baoji City is situated in the upper reaches of the Weihe River. The water quality research of Weihe River in Baoji section and wastewater treatment influence on water quality are both important. By using the one-dimension dilute self-purification model, and based on hydrology and water quality data, the paper predicted the improvement degree of the Weihe water quality after the construction of city wastewater plant under the different guarantee rate. Based on the present water pollution status and wastewater drainage of Weihe River in Baoji City, the water quality of the Weihe River inside Baoji section is calculated respectively before and after the establishment of wastewater treatment plant. With referonce to the wastewater treatment engineering plan and eco-city construction plan, we compared the water environment system before treatment with that which has been treated, and concluded that the plan of wastewater treatment of Baoji city will benefit the construction of an ecological city.
